  1. Practical Applications of Systems Thinking and STELLA in the High School Setting Presented by: Jeremy Merritt, Mark Clemente VSTE 2009

  2. “A system is an interconnected set of elements that is coherently organized in a way that achieves something” Donella H. Meadows, Thinking in Systems: A Primer (Chelsea Green Publishing, 2008) 11 What is a system?

  3. Examples of Systems Digestive Forest Community

  4. Slinky

  5. Bathtubs A bathtub is a simple system

  6. Bathtub System Draining 1: Bathtub 1: 30 1 1 1: 15 1 1 1: 0 0.00 7.50 15.00 22.50 30.00 Minutes 11:46 AM Fri, Feb 20, 2009 Water in bathtub

  7. Understanding Behavior Over Time Dynamic Equilibrium 1: Bathtub 1: 26 1 1 1 1 1: 25 1: 24 0.00 7.50 15.00 22.50 30.00 Minutes 11:34 AM Fri, Feb 20, 2009 Water in bathtub

  8. Stocks & Flows The bathtub is a stock

  9. Stocks & Flows The faucet and the drain are flows

  10. Modeling Systems with STELLA

  11. Other Stocks & Flows Same thing, different units

  12. Feedback Loops A feedback loop occurs when a stock affects its flows R

  13. Feedback Loops Reinforcing Loops R R R

  14. Behavior vs. Data It’s important to focus on behavior when you’re thinking about systems 1 R 1 1 1

  15. Feedback Loops Balancing Loop

  16. Balancing Loops 1: Population 1: 450 1 1 1 1: 250 1 1: 50 0.00 15.00 30.00 45.00 60.00 Time

  17. Applying Systems Thinking in the Classroom Non-software-based Software-based Use Systems Thinking Stock & flow Mapping Use Model-based Concepts Materials

  18. Earth Systems Science & STELLA An example: GLOBE Carbon Cycle Program • Bringing cutting edge research & techniques into the classroom • STELLA models that use input data collected by students and researchers • Focus on using technology & modeling to give students an understanding of local and global carbon cycles

  19. Lessons in Mathematics Lessons in Mathematics: A Dynamic Approach by Diana Fisher provides a set of materials that can be used to supplement current curriculum for Algebra I, Algebra II, Pre-Calculus and Calculus classes.
